Grade Four: Prolapse that cannot be pushed back in by the patient (often very painful)īleeding attributed to internal hemorrhoids is usually bright red and can be quite brisk. Grade Three: Prolapse that must be pushed back in by the patient Grade Two: Prolapse that goes back in on its own Internal hemorrhoids are classified by their degree of prolapse, which helps determine management: The symptoms tend to progress slowly over a long time and are often intermittent. This tissue often goes back inside spontaneously or can be pushed back internally by the patient. Prolapse is hemorrhoidal tissue coming from the inside that can often be felt on the outside of the anus when wiping or having a bowel movement. Painless rectal bleeding or prolapse of anal tissue is often associated with symptomatic internal hemorrhoids. Other serious diseases such as anal and colorectal cancer should be ruled out by a consultation with physicians knowledgeable in evaluating the anal and rectal area. Some patients will have long-standing complaints that are not attributable to hemorrhoidal disease. The majority of patients with anal symptoms seen in a colon and rectal surgeon’s office complain of their hemorrhoids but a careful history and examination by an experienced physician is necessary to make a correct diagnosis. Patients may experience symptoms caused by either internal or external hemorrhoids or both. Roughly 5% of people will develop symptoms attributable to their hemorrhoids and only a small fraction of those patients will require surgical treatment. When problems develop, these two types of hemorrhoids can have very different symptoms and treatments. Internal hemorrhoids are covered with a lining called mucosa that is not sensitive to touch, pain, stretch, and temperature, while external hemorrhoids are covered by skin that is very sensitive. There are two main types of hemorrhoids: internal and external. Hemorrhoidal tissue lies within the anal canal and perianal area and consists of blood vessels, connective tissue, and a small amount of muscle. Only in a minority of people do hemorrhoids become enlarged or otherwise symptomatic. It is important to note that all people have hemorrhoidal tissue as part of their normal anatomy.
